5 Routine Checks
Although the system is intended for continuous un-attended operation
, it is recommended that the user
regularly check that images from all cameras replay correctly.
Any potential problems with the cameras
or recording system will then be detected as soon a possible, rather continuing un-noticed until a critical
incident needs to be recalled from the system.
Similarly,
when a CD has been created you should check that it plays back correctly
, before the
images are over-recorded on the VDM. The CD may be checked by either by playing it on a VDM or on a
PC.
If a red “Critical Alert” message appears on the screen, this indicates to the user that a fault condition has
been automatically detected that could affect recording. The nature of the alert should be checked in the
events screen and appropriate action taken.
5.1 Critical Alerts
The VDC constantly monitors the hard drive, camera inputs and system so that detected fault conditions will
be reported to the user as soon as possible by means of a “critical alert” message on the screen. Alerts are
also added to the event list.
Press the
EVENTS
key to view the event list (pressing the
DEFAULT
key automatically scrolls to the most
recent events.
Viewing the list will cancel the alert message. However if the condition persists, the message will re-appear.
